connector on a backplane. A SATA II connector consists of a signal
connector and a power connector.
Figure 2.3 SATA II Connectors
Figure 2.4 shows SAS connectors and SATA II connectors on SAS
physical disks and SATA II physical disks, respectively. Cables are used
for connection between internal connectors on the RAID controller and
connectors on SAS drives and/or SATA II drives, respectively. Both SAS
physical disks and SATA II physical disks can connect to SAS backplane
receptable connectors. The difference between the SAS connector and
SATA II connector is the bridge between the SAS primary physical link
and the power connector on the SAS controller, which the SATA II
connector does not have.
Note: SAS backplane connectors can accept SAS physical disks
or SATA II physical disks, but SATA II backplane
connectors
cannot accept SAS drives.
